I did not meet Pornpan.
The apartment is fine and you can get to all places in Bangkok from here. A few things people need to be aware of:
Getting to the apartment from the airport can be a bit tricky - the subway system works very well but I would strongly advise you get a map of the whole system before you arrive as there are none on the platforms. There is one on the Thai airlines website. Whilst there are written directions as to how to get to the apartment from the station a simple map would really help.
This is the only AIRBNB place I've stayed where I could find no information e.g. Where to put the trash, but Pornpan does respond well to emails.
